Ms. Pac-Man is on the tricky list for needing the vblank flag (bit 7 of $2002) to read back as 1 if vblank begins in the middle of the lda $2002 instruction. Spelunker and Lolo 2 are on the tricky list for the same reason; do they also break?

Sounds like this should be one that needs to get fixed in the GoodNES tools then, i.e. ROM should have the correct mirroring value set in the NES header. I have no idea presently how to report issues like that to Cowering. I also wonder if there are other Tengen NROM games that might need the same.

The Nestopia game database is ridiculously huge. So many overrides/tweaks for incorrect headers in ROMs. :(

The [oX] nomclature comes from GoodTools, which means "overdump", hence those are bad dumps. You can see evidence of this from the file sizes. The only one that's correct (and I can tell from the file size alone) is Ms. Pac-Man (U) (Tengen).nes. Here are MD5s for all of them anyway:

Next, given the timestamps of these ROMs, it's safe to say they were run through GoodNES a very long time ago. This is important because Cowering has certainly changed/fixed many issues in the past 16 years. ;-) So let's run these through GoodNES/GoodTools (latest is April 2016) and see what happens. Again, we're focused on Ms. Pac-Man (U) (Tengen).nes.

All horribly off-topic. The person said I needed, meaning he went looking for a ROM with proper headers and found it. Past-tense.

As for an uploader tool "fixing ROMs" on-the-fly: I disagree strongly. The uploader tool should have no involvement in such things; it should upload what you give it, period. Think of an EEPROM writer/burner "magically changing your data" without your knowledge -- all this does is create problems.

The ROMs should be fixed/repaired prior. That's what GoodTools is for.
